Plans have been lodged for 820 homes in County Meath,
They've been lodged with An Bord Pleanála, under the new fast-track mechanism for large developments.
The plans include 336 houses and 484 apartments near the railway station in Dunboyne, and the proposed development would also include two creches and other facilities.
A company owned by veteran racehorse owner and breeder John Connaughton has opened talks with planners about building the 820 homes.
Local Fine Gael councillor Maria Murphy isn't in favour of the plans, with her main concern being population density.
"This is the second large application we've had in the area in the last few months. The first one was for a site in Dunshaughlin which was approved by An Bord Pleanála for over 900 units."
"We do need starter homes in Dunboyne for our young people, but we do need a balance of development on any site, and I was just be keeping an eye on the density."
